How is Silk Fibroin Processed for Nanotechnology Applications?
Silk fibroin is typically extracted from silk fibers through a process that involves degumming to remove sericin, the protein that coats fibroin. The fibroin is then dissolved in solvents like lithium bromide or formic acid. This solution can be used to create nanofibers through electrospinning, nanoparticles through desolvation, or films through casting.
